​
Watching Our Waters: An Update on Agricultural Water Quality Monitoring in California

State agencies such as the State Water Resources Control Board, Regional Boards, and the Department of Water Resources are charged with protecting the integrity of state waters and ensuring access to high-quality drinking water for all Californians.  Over the years, health effects of contaminants like agricultural nitrates and artificial per- and polyfluoroalkyl substances (PFAS) have prompted federal, state, and local agencies to take action.  Agencies have devised ambitious plans, leveraging innovative technologies and policies, to detect, monitor for, and remove pollutants and contaminants from state waters.  This discussion will focus on the effects of agricultural operations on surface and groundwater sources.  In this context, panelists will discuss current regimes, established goals, and future directions for statewide monitoring, as stakeholders strive to develop and comply with continuously evolving standards.

Panel 2 I Organized by USF School of Law
Reviving Tulare Lake: Legal and Environmental Challenges in the
Face of Water Scarcity and Restoration

The Tulare Lake Basin, once the largest freshwater lake west of the Mississippi, has a rich and complex history that intertwines natural ecosystems, Native American heritage, and modern water law. After centuries of supporting diverse ecosystems and human populations, the lake has largely disappeared due to water diversion for agricultural and municipal use. The lake’s intermittent reappearance, such as in 2023, underscores the dynamic nature of California’s water systems and the challenges of managing both surface water and groundwater resources in a state facing increasing climate variability. In 2023, during a period of high rainfall, Tulare Lake briefly reemerged. However, this was accompanied by legal and environmental concerns, including rising pollution levels and the consequences of decades of over-extraction. The California State Water Resources Control Board placed the Tulare Lake Sub-basin under probation in recognition of these issues, and the ongoing legal uncertainty surrounding the Sub-basin's management continues to impact
groundwater extraction and related policies.
​

This symposium will explore the complex intersection of water law, environmental policy, and indigenous rights in the context of Tulare Lake's history, its current legal standing, and future challenges.

Panel 3 I Organized by Stanford Law School and UC Berkeley School of Law
​Legal Considerations in Wastewater Recycling

In December 2023, the California State Water Resources Control Board unanimously approved standards for turning wastewater into drinking water. Supporters praise the move as a climate-resilient source of drinking water as the state grapples with persistent drought and water scarcity. Critics raise concerns about the cost, enforcement, and monitoring, calling the process “toilet-to-tap.” On October 1, 2024, California's new Direct Potable Reuse (DPR) regulations went into effect. Our expert panelists will talk about their work in research, policy, and advising as we explore the history of California’s recycled water projects and current challenges to introducing DPR into the state's water system.

Panel 4 I Organized by University of the Pacific, McGeorge School of Law and UC Davis School of Law
​
Tribal Sovereignty and Stewardship of California's Aquatic Ecosystems

Native American tribes are sovereign governments in the United States but have often been deprived directly or indirectly of the fundamental right to manage their lands and steward fish and wildlife on tribal lands and waters. State, federal, and tribal governments are seeking opportunities to rectify this historic wrong and engage tribes in stewardship of California’s waters. Direct tribal management is one approach, and tribal water rights also play a role. Another mechanism gaining attention in recent years is the use of collaborative or cooperative sovereign-to-sovereign agreements between tribes and state or federal agencies. In 2024, California enacted a bill (AB 1284) that authorizes and supports sovereign-to-sovereign co-stewardship agreements, providing a pathway for integration of traditional ecological knowledge into decisions affecting California’s rivers, fish, wildlife, and habitat. 

​
This panel will explore the tribal role in protecting aquatic ecosystems in California, discussing direct tribal management, sovereign-to-sovereign agreements, and the role of tribal water rights. Tribes, government, and practitioner representatives will describe concepts of tribal sovereignty vis-à-vis state and federal sovereignty, and will be invited to share perspectives on differing relationships to the natural world. The panelists will assess existing and potential agreements for sharing stewardship of California’s rivers and aquatic ecosystems, and explore other mechanisms for supporting greater integration of tribes as sovereigns into California freshwater management.

In his words, “the future of humanity has only looked so bleak a few times in the past, but we are also so close to becoming the best we ever could. Letting everything humanity has achieved die because we are to dumb to stop burning trees from before history feels like the stupidest possible way to go extinct.” Sean wants to make sure that there is a tomorrow for everyone, and believes the best way to do that is be a part of the process, understanding it, and working it!
